Application filed December 1 To all whom it may concern:

Be it known that l, Aunnosn H. SAss'AMAN, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Journal-Bearings, of which the following is a specification.

My invention relates to journal bearings and has for its object a simple and effectual means for lubricating the bearing and at the same time providing for a minimum amount ofiriction by furnishing the journal with roller bearings having lubricating means so arranged as to further reduce the Wear and friction, as will be further explained in the following specification, set forth in the appended claims and illustrated in the accomanying drawings, where'it will be seen that like reference characters are used to designate the same part in the various figures.

Figure 1 is a sectional view of the journal box looking towards the front of the journal. Fig. 2 is a cross-section of the journal box; on line with the journal. Fig. 3 is a perspective view of the hearing piece, looking at its Fig. 4 is a view of the same bearing piece from its under side. r

This invention is adapted to reduce the friction. of the journal on its bearing to a minimum and at the same time provide this reduced bearing surface with suflicient lubri cation to cause the journal to run with a minimum amount of friction and wear, and in order to provide for this feature I nrovide an ordinary journal box 6 such ordinarily used on railroad cars with a bearing niece of the form shown in the various figures. This bearing piece 7 is practically a block of hard metal having its under surface cone en 4c trio with the journal and recessed as 8,

the ribs 9 forming sides or ends for these recesses and having sockets 15 forming hearlugs for the reduced. ends of roller. ll. The larger portions of the rollers ".1 lie in the reccsses 8 and bear upon one side of the journal l2. with the bearing piece is at their journals formed by the reduced ends 13 and the re The only contact which the rollers have hearing piece, and channels duced section 14 at their centers. Entering these sockets 15 in the bearing pieces are small orifices '16 which communicate with grooves 17 around the outer surface of the bearing block and which are adapted to carry wicks 18 which pass down into the lower part of the journal box and carry the oil therefrom to the upper surface of the block from whence it runs down the orifices and lubricates the reduced portions 13 of the rollers 11.

While it will be seen that I have shown the journal block provided with two rollers I do not limit myself to any particular number. Likewise there may be more of the ribs 9 than the number I have illustrated and the number of grooves 17 may be likewise varied to correspond with the ribs in order to provide the necessary lubrication for the reduced portions of the rollers 11. The jour nal box is as usual provided with the cotton waste 19 which applies the oil or grease to 7 the aide ournal itself and thus lubricates the bearing sections 13, 141 of the rollers where they come in contact with such ournal.

What I claim as new and desire to'secure by Letters Fatent is: 7

ln. combination with a j ournahhox and. an axle-journal extendin thereinto, a bearing piece disposed opposite one side of the axlejournal and having an inns concaved face provided with alternating ribs and recesses, the ribs dividing said recesses and being formed with open hearing sockets, the outer face of hearing piece having shallow transv rse grooves at points opposite the respective ribs and communicating vertical grooves extending down upon the sides and through the edges or the hearing of the.

leading at an angle from the points of intersection of said transverse and vertical grooves to the said open bearing sockets, lubricant conducting wicks disposed in such grooves and extendinto the ournal-borr, and antifriction rollers interposed between the bearing and axle-journal, and having reduced our Q5 nals mounted in the open heariiox soclretsof the bearing iece, said journals being re- Iii testimony whereof, I aflix my signature tained in sai sockets agginst displacement in presence of two Witnesses. in the axle-journal by t e pressure of the I latter, whereby the rollers are free for re- AMBROSE SASSAMAN' 5 moval from the. bearing sockets when the i Witnesses:

bearing piece is removed from the journal- JAMES F. DUHAMEL, box. H; G. HOSE.
